The CPU is known as the "brains" of the computer, processing instructions and allowing the computer to operate software and execute complex tasks.
The "brains" of the computer is considered to be the CPU, which stands for Central Processing Unit. Just as the brain processes information in humans, the CPU processes instructions in a computer. It performs the basic arithmetic, logic, control, and input/output operations specified by the instructions in the program. This critical component is what enables computers to execute complex tasks and operate software. In the history of computing, various materials and technologies have been used to create computers. Early on, mechanical components were used, as in Charles Babbage's 1833 design for the Analytical Engine, but now computers are made primarily from transistors and silicon chips, facilitating rapid data processing.
